Solution

The correct option is C
2v/t

Average velocity = (u+v)/t

Acceleration = (v-u)/t

Thus sum of average velocity and acceleration = (u + v )/t + (v-u)/t = 2v/t

If the velocity of a body changes uniformly from u to v in time t, the sum of average velocity and acceleration is:

The correct option is C 2v/t Average velocity = (u+v)/t Acceleration = (v-u)/t Thus sum of average velocity and acceleration = (u + v )/t + (v-u)/t = 2v/t

The correct option is C
2v/t

Average velocity = (u+v)/t

Acceleration = (v-u)/t

Thus sum of average velocity and acceleration = (u + v )/t + (v-u)/t = 2v/t
